you have many linux! you must really be good in linux. i want a linux that installs only one file and not request another required to run. what linux is that?

Use Debian or something based on Debian (like Xandros). That way, you can use their graphical package managers or the classic "apt-get" command to download and install applications. It will get everything that an app needs to get running if the app in question is in their database.
